15. draining the water level reading from the pressure sensor has not changed for over 3 minutes There are three likely reasons for this fault One is that the drain hose or the pressure switch hose has been squashed or kinked and the pump out rate has been dramatically reduced The second possibility is that the pump is partially or fully blocked The third is that the pump is not operating due to Motor Control Module wiring or pump failure This fault could also appear if the machine is pumping to an unusually high head of drain hose or into an extended length of drain hose The fourth possibility is a recirculation valve fault or blockage water level is not altering as the recirculation valve is stuck in the recirculating mode giving the module the appearance the pump is not lowering the water level Primary Source Pump System Action 1 Check that the drain hose has not been kinked 2 Check the length of the drain hose and try to reduce the length if excessively long A 39 36in 1 metre extension hose of the same diameter fitted to the existing drain hose is the maximum allowable extra length 3 Check for open circuit windings in the pump Note Pumps are fitted with a thermal cut out which will reset on cooling 4 If the basket is empty of water remove the pump from the pump housing and check that it is not blocked Also check the drain hose is not blocked 5 If the basket contains water then service the pump from the top of the m
